Run-time ussues:
* Fix comparison of negative numbers that happen to be equal.
* Fix bad execution of certain expressions caused by code generator
bad lookaside handling.
* Proper error message for invalid bit selects.
* Implement $printtimescale system task.
Compiler build issues:

Release Notes for Icarus Verilog 0.8.4
This is a bug-fix release for the 0.8 stable branch. The 0.8 stable
branch updates do not include significant new features (they go into
the devel branch instead) nor fixes that are deemed to drastic to
include in a stable tool.
- Various source code portability problems have been fixed. The 0.8 no
longer compiles on many modern systems.
- Various bug reports have been put to rest with this release. Some
parser errors have been fixed (including a few regressions from
0.8.3) and a few new syntaxes added.
- A variety of systhesis bug fixes and enhancements are included in
0.8.4. Currently, synthesis is only actively supported in the 0.8
branch, and the 0.8.4 is the most complete.
